Mental rotation of letters, pictures, and three-dimensional objects in German dyslexic children. 总被引:1,自引:0,他引:1

This study examines mental rotation ability in children with developmental dyslexia. Prior investigations have yielded equivocal results that might be due to differences in stimulus material and testing formats employed. Whereas some investigators found dyslexic readers to be impaired in mental rotation, others did not report any performance differences or even superior spatial performance for dyslexia. Here, we report a comparison of mental rotation for letters, three-dimensional figures sensu Shepard and Metzler, and colored pictures of animals or humans in second-grade German dyslexic readers. Findings indicate that dyslexic readers are impaired in mental rotation for all three kinds of stimuli. Effects of general intelligence were controlled. Furthermore, dyslexic children were deficient in other spatial abilities like identifying letters or forms among distracters. These results are discussed with respect to the hypotheses of a developmental dysfunction of the parietal cortex or a subtle anomaly in cerebellar function in dyslexic readers. 相似文献

In this article, normative data on the familiarity and difficulty of 196 single-solution Spanish word fragments are presented. The database includes the following indices: difficulty, familiarity, frequency, number of meanings, number of letters given in the fragment, first and/or last letters given, and ratio of letters to blanks. A factor analysis was performed on difficulty, and two factors were obtained. Frequency, familiarity, and number of meanings loaded highly on the first factor, which we consider to measure lexical processes, whereas number of letters in the fragment, first and/or last letters given, and ratio of letters to blanks loaded highly on the second factor, which we judge to be determined by perceptual information. Regression analyses using factor scores as predictors showed that both factors accounted for a significant part of the completion probability scores. The full set of these norms may be downloaded from the Psychonomic Society Web archive at www.psychonomic.org/archive/. 相似文献

This article analyzes the global proliferation of discourse about gay penguins in zoos. Based on internet-based representations, we identify a directional narrative logic of “gay penguin discourses” in which the ideal gay penguin comes out as gay, falls in love, follows natural desires to parent, and may marry as a reward. This discursive chain is animated by the zoo as institutional space of captivity, which incites human subjects to become agents in its reproduction. In contests over penguin actions and morality, zookeepers, gay activists, and conservative family groups reiterate a homonormative politics of identity through talk of discrimination and rights. To identify what makes this discourse seem real, we draw on Ahmed’s Queer Phenomenology to analyze the composition of the zoo as the site of a particular “mode of address” that orients humans to adopt positions of authority, evaluation, and regulation. Three orientations—reason, emotion, and instinct—function as an assemblage whose elements connect and separate, such that when one orientation’s ability to explain penguin behaviors is exceeded, another orientation steps in or connects with the first to supply a logic that confirms the discursive chain for the ideal gay penguin and how humans can meet his needs. Locked into logics of hetero/homo, oriented through reason, instinct, and emotion, and interpellated through emotions, humans can imagine little more than an anthropocentric repetition of our own “progress.” The future, for humans and penguins, is secured. 相似文献

Cognitive insight is the ability to monitor and correct one's own erroneous convictions. The Beck Cognitive Insight Scale (BCIS) assesses two sub‐dimensions of cognitive insight: self‐reflectiveness (SR), which is the attitude of questioning one's own judgments; and self‐certainty (SC), which is the unwillingness to modify and correct one's own convictions. There is little information about cognitive insight in healthy participants (HP). Here we investigated the socio‐demographic and neuropsychological correlates of cognitive insight in 50 HP who were administered the BCIS and a comprehensive neuropsychological battery. The global BCIS R‐C index correlated positively with age and WCST perseverative errors. SR correlated positively with age. These data support the hypothesis that a less self‐reflective and more self‐confident style is cognitively functional in HP. Thus, what has been found malfunctioning in mental illnesses is adaptive in HP. Future studies should consider a wider range of factors that might affect this complex construct.

The capacity to reason about the false beliefs of others is classically considered the benchmark for a fully fledged understanding of the mental lives of others. Although much is known about the developmental origins of our understanding of others' beliefs, we still know much less about the evolutionary origins of this capacity. Here, we examine whether non-human primates - specifically, rhesus macaques (Macaca mulatta) - share this developmental achievement. We presented macaques with a looking-time measure of false belief understanding, one that had recently been developed for use with 15-month-old human infants. Like human infants, monkeys look longer when a human experimenter fails to search in the correct location when she has accurate knowledge. In contrast to infants, however, monkeys appear to make no prediction about how a human experimenter will act when she has a false belief. Across three studies, macaques' pattern of results is consistent with the view that monkeys can represent the knowledge and ignorance of others, but not their beliefs. The capacity to represent beliefs may therefore be a unique hallmark of human cognition. 相似文献

This two-wave longitudinal study examines the ability of life satisfaction and adjustment strategies to predict anxious and
depressive symptoms in coronary heart disease male patients. Studies have shown that most heart attack survivors report these
symptoms, which may worsen the prognosis of the disease. At Time 1, immediately after the first cardiac episode, eighty-eight
men reported their life satisfaction levels, adjustment strategies used, and anxious and depressive symptoms experienced.
At Time 2, six months later, sixty-three of those patients reported only their anxious and depressive symptoms again. The
results showed that, after controlling for demographic variables, anxious and depressive symptoms at Time 1 were predicted
by positive adjustment and life satisfaction. At Time 2, after controlling for both demographic variables and Time 1-emotional
symptoms, none of the psychological variables predicted anxious symptoms, while depressive symptoms were only predicted by
life satisfaction. It is concluded that an adequate level of life satisfaction may help to decrease emotional distress, both
short and long term, while the use of positive adjustment strategies is especially important immediately after diagnosis. 相似文献

This study explores the moderating effects of various consumer features – such as price insensitivity and recency of last purchase – on the relationships among perceived value, inferred vendor profit, and perceived price fairness. A proposed model is developed and an empirical study is then conducted among consumers in four contexts: (i) two tangible goods; and (ii) two intangible services. The proposed model and hypotheses are tested using Partial Least Squares (PLS) software SmartPLS 2.0.M3, which provides a component‐based approach for estimation purposes. The influence of these moderating variables (price insensitivity and recency of the last purchase) depends on the context and the nature of the offering. This is a pioneering study of perceived price fairness in a framework of distributive justice utilizing a variety of contexts, products, and services. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献
